Question

// src/Acme/DemoBundle/Tests/Controller/DemoControllerTest.php
namespace Acme\DemoBundle\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class DemoControllerTest extends WebTestCase
{
    public function testIndex()
    {
        $client = static::createClient();

        $crawler = $client->request('GET', '/demo/hello/Fabien');

        $this->assertGreaterThan(0, $crawler->filter('html:contains("Hello Fabien")')->count());
    }
}

this working OK in my tests, but i would like use this crawler also in controller. How can i do it?

i make route, and add to controller:

<?php

// src/Ens/JobeetBundle/Controller/CategoryController

namespace Acme\DemoBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Acme\DemoBundle\Entity\Category;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class CategoryController extends Controller
{   
  public function testAction()
  {
    $client = WebTestCase::createClient();

    $crawler = $client->request('GET', '/category/index');
  }

}

but this return me error:

Fatal error: Class 'PHPUnit_Framework_TestCase' not found in /acme/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Test/WebTestCase.php on line 24

Answer 1

The WebTestCase class is a special class that is designed to be run within a test framework (PHPUnit) and you cannot use it in your controller.

But you can create a HTTPKernel client like this:

use Symfony\Component\HttpKernel\Client;

...

public function testAction()
{
    $client = new Client($this->get('kernel'));
    $crawler = $client->request('GET', '/category/index');
}

Note that you will only be able to use this client to browse your own symfony application. If you want to browse an external server you will need to use another client like goutte.

The crawler created here is the same crawler returned by WebTestCase so you can follow the same examples detailed in the symfony testing documentation

If you need more information, here is the documentation for the crawler component and here is the class reference
